The check-in process was very smooth - we arrived a little earlier than check-in time and instead of asking us to store luggage and come back, the friendly front desk employee found a clean room available for us! She even provided a map and recommendations for a tour. Thankfully, the quick check-in allowed us to start exploring immediately. Also, cool that they use real keys instead of magnetic cards.
The room itself was clean and nice-sized. Our bathroom's fan and shower light were not in service, but it did not affect us too much. We made use of the mini refrigerator, iron, and ironing board and they all worked well.
This is a beautiful hotel with brick interior, nicely decorated with harbor and nautical art. The hotel has two working elevators, and we had no issues with long waits. The hotel is perfectly located for exploring nearby Quincy Market and Faneuil Hall, and walkable to many nearby attractions.
Overall, we had a pleasant stay and highly recommend the Harborside Inn. One tip for management to take it to A+ would be to consider including free breakfast or a morning snack to hotel guests.
